PROCEDURE
|
1. |
RECONFIRM DTC |
HINT:
These codes are detected when a problem is determined in the skid control ECU (brake actuator assembly).
The solenoid circuits are in the skid control ECU (brake actuator assembly).
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if any DTCs are output before replacing the skid control ECU (brake actuator assembly).
(a) Clear the DTCs.
Chassis > ABS/VSC/TRAC > Clear DTCs
(b) Turn the ignition switch off.
(c) Start the engine.
(d) Drive the vehicle at a speed of 20 km/h (12 mph) or more.
(e) Check if the same DTC is output.

Result |
Proceed to |
|---|---|
|
Both C1225, C1226, C1227, C1228, C1468, C1469, C146A and C146B are not output |
A |
|
C1225, C1226, C1227, C1228, C1468, C1469, C146A or C146B is output |
B |
HINT:
- The skid control ECU (brake actuator assembly) performs self diagnosis of the solenoid circuit after the ignition switch is turned to ON.
- If the normal system code is output (no DTCs are output), slightly jiggle the connectors, wire harness, and fuses of the skid control ECU (brake actuator assembly).
- If any DTCs are output while jiggling a connector or wire harness of the skid control ECU (brake actuator assembly), inspect and repair the connector or wire harness.
- If no DTCs were output when reconfirming DTCs, checking for intermittent problems is necessary because it is suspected that the original DTCs were stored due to the poor connection of a connector terminal.
